"There are no HI-SPEED USB host controllers installed on this computer"

Thanks Dis. I purchased this computer 3 months ago and all the slots support USB 2.0.

Check these microsoft pages out ... maybe they will help

Also have you tried going to the Windows Update site and downloading updates....I believe that in some instances depending on your hardware...there will be a USB driver for XP....I believe this is the same driver you will get from here:

Hope this helps

Thanks again Dis. Yesterday I upgraded to Service pack 2 so there's no patch left to install. I tried with USB 2.0 Dell drivers too. I also uninstalled and reinstalled these devices.

Thanks Netman66, I just checked the bios and it gives me the option to turn on/off  USB and USB emulation (they are both turned on). Regards,

Try turning emulation off.  I think emulation for Dell means USB Legacy support - meaning if you have a USB keyboard it will work during the POST.  This setting might actually hold the ports to USB 1.1.

Advise.

Thanks netman66,

I disabled USB emulation but I still get the error "No Hi-speed host controllers intalled on this computer".

Bummer....I think a call to Dell might be in order.  You should have free support on that, just give them your Service Tag number when you call.

Confirming dis1921's comment: you are using a USB 1.0 connection, or that is the way the machine is seeing it.

According to Dell's site, All USB slots on your machine are 2.0 compatible, so that shouldn't be the problem.

By any chance, are you using a USB hub to connect this device?  If so, it also needs to support USB 2.0.  If not, I agree that a call to Dell may be in order.  Before you call, you might test the device you're trying to connect (camera, memory stick) on another machine to verify it is working properly and is USB2.0 compatible.

Good luck!

Have you tried to re-install the usb driver from XP...yes i know you installed SP2 as you said before...but try it anyway if you haven't there have been numerous problems with this...I've had this issue before as well and the re-install driver worked in my case....give it a try if you haven't though i know it hasn't worked for everyone.

Thanks to all experts on this threat. I have emailed Dell and as soon as I get a solution I'll post it here. I will also try to re-install usb drivers as dis1931 recommends.

I just got a reply from Dell. They're not helping me as I purchased it with XP home SP1 and I have XP pro SP2 now.

I removed all USB host controllers and restarted the pc, but I still can't get USB 2.0.

Thanks for your help.

According to the Dell product page for your machine, they offer XPpro as an option for this machine, so the hardware should be compatible and support should be familiar with it (read: have scripts to regurgitate for XPpro).

Sine it has never worked (even on SP1), I'm suspecting drivers rather than hardware/BIOS (assuming it worked with XPhome?).  I would reset your BIOS back to the way it was (undo the changes you list above).

Since the USB ports are integrated into the main board, you probably need to grab the Intel chipset drivers from Dell's site and install them.  

Dell Support: http://support.dell.com/
click downloads, and type in your service tag (or select your machine type).  Look for under "Chipset" category for WinXP and it should take you right to the download.

Good luck!

Thanks syncubus. I updated the Bios, and then the chipset drivers (*). Sadly, I still get "There are no HI-SPEED USB host controllers installed on this computer".

Be sure that the hardware you are running functions correctly:

Try a different set of USB slots - e.g., if you're using the front slots, try the back ones (or vice versa).  Most Dell machines have USB slots on the back of the machine and on the front (under a liftup faceplate).

Make sure another USB 2.0 device gives you the same error on your machine.  This will help rule out the possibility that your USB device (the iPod) is at fault.

Make sure your USB 2.0 device is recognized properly on another machine (similar to the above).  many people don't have another machine at their disposal, but a friend may have one you can plug into to verify that your iPod is working properly.

This will help determine whether it is a problem with the USB device or with your machine.  It will also eliminate a bad USB connector set.  It would be a shame to have been troubleshooting the machine, when the problem lies with the iPod.

I have a wedding tomorrow, so I'll try that on sunday. Thanks syncubus.

Sorry for the delay. Well, I've tested the ipod in another machine with a USB 2.0 port and it works fine. All USB ports on my machine (front, back, plus the ones on the monitor) work at reduced speed. Should Dell service my machine if I purchased it with XP home and I'm on XP pro now? Thanks.

Eureka!!!!!! Thank you so much!

Following your instructions I went to the device manager. I saw a device with a warning sign (not under USB controllers though) and I updated its driver. To my surprise it ended up being a USB2 Enhanced host controller!!!

Thanks to Dis1931, Netman66 and Syncubus for your help!

Glad we got it worked out!
